What is the Required Capacitor KVAR for 50 HP Motor?
The motor draws inductive current when a 50 HP induction motor is run by feeding a three-phase AC supply. At the no-load running of the
Difference between Active and Passive Components
In this post, we will discuss the difference between Active and Passive components. We can differentiate active & passive components on the basis of the
Difference between Capacitor and Battery
The difference between capacitor and battery lies in how they store and deliver energy. A capacitor stores energy in the form of an electric field,
What is Battery Acid? Its composition and Roles
Battery acid is a dilute solution of sulfuric acid (H₂SO₄) used in lead-acid batteries. Comprising 29%-32% sulfuric acid, it facilitates the flow of electrical current
Why is the Terminal Voltage Less than EMF During Discharging of Battery?
The terminal voltage of a battery is less than its EMF because of the internal resistance inside the battery that causes a voltage drop when
Eddy Current Theory and Applications
